Built using the latest injector technology, these injectors deliver exceptional linearity, outstanding short pulse width repeatability, and excellent drivability for naturally aspirated, supercharged, and turbocharged performance applications.
This injector set features easy-to-install, drop-in fitment with the factory style connector. No plug conversion is required. Depending on your application, fuel rail spacers may be required, and the necessary spacers are included with the kit. Fuel Injector Clinic also provides Plug and Play GM ECU calibration data for supported GM engine management systems, making tuning easier while maintaining factory-like idle quality and drivability.
Every injector set is precisely matched using Fuel Injector Clinic's proprietary Data Match Technology. Each injector is individually serial numbered and supplied with a detailed Data Match Sheet containing injector-specific flow and latency values, providing industry-leading injector consistency and cylinder-to-cylinder fuel delivery.
